Testing solution structures with commands.

[Vanderkast]

Some problems require implementation Structures that tested with method call sequence.
Example: leetcode id 380.

Input
["RandomizedSet", "insert", "remove", "insert", "getRandom", "remove", "insert", "getRandom"]
[[], [1], [2], [2], [], [1], [2], []]
Output
[null, true, false, true, 2, true, false, 2]

In input we have 2 arrays:

1. Method calls sequence. Contains method names that should be called.
2. Method call sparameters sequence. Contains array of method parameters passed to methods from sequence 1.

In output we have expected values to be returned on method calls from input.
